The 59-year-old will join a group of 65 mountain bikers, who will cover 3384km of bush trails collectively.
Mr Halford hopes to ride 64km for the event.
The race raises funds to beat muscular dystrophy.
�I�ve been riding for about four to five years,� Mr Halford said. �I saw something about the Ride for Someone Who Can�t and thought it was a good cause and signed up.�
He will be riding for 17-year-old Dylan Stewart, who has a form of muscular dystrophy.
